BIOPHYSICAL CHEMISTRY ESSAY: CELL MEMBRANE STRUCTURE AND PURPOSE Introduction. Cell membrane is a biological barrier that separates the interior part of the cell (i.e. the Cytoplasm, nuclei and the other cell organelle) from the outer environment, thus permits cellular individuality and also gives shape to the cell.
In eukaryotic cells, the synthesis of membrane proteins destined for the plasma membrane, ER or any other membrane-bound compartment begins on cytosolic ribosomes. After a short segment of protein has been synthesized, the ribosome, mRNA and nascent protein chain associate with the ER, where the rest of the protein is made and simultaneously inserted into the membrane.
The plasma membrane also known as the cell membrane is found in every cell. The cell membrane is around 7-10nm, making it difficult to view even with a transmission scanning electron microscope (it only shows a double black line), this means that no one knows exactly what the membrane looks like.
Essay text: This causes a semi permeable barrier that is called the plasma membrane. Semi permeable means that some things are able to pass through while others are not. When molecules are transported though a membrane using either method, it is called diffusion.
Essay text: Most, but not all, lipids are referred to as phospholipids. These lipids arrange themselves into the bilayer. Another lipid is the glyolipid, which are a protective lipid and performs a variety of functions within the membrane.

Give chemical composition of plasma membrane. Ans: Protein: 60 to 80%. Phospholipids: 20 to 40 %, Cholesterol in small amount. Carbohydrates in small amount. What was the model of E. Gorter and F. Grendel? Ans: They described that cell membrane is actually phospholipids bilayers. The hydrophobic ends of the phospholipids molecules are directed inward and hydrophilic ends of the membrane are.
Plasma Membrane. The cell, which is the smallest unit of life, is surrounded by a plasma membrane.The plasma membrane functions somewhat like a wall, as it keeps the internal contents from the external environment. Just like a wall, the membrane is also somewhat permeable, except that the membrane takes a much more active role in determining what is allowed in to the cell and what is kept out.
Plasma Membrane. Plasma membrane targeting of HIV-1 Gag is mediated through a bipartite signal consisting of a myristic acid moiety added to the second amino acid of MA, which inserts into the plasma membrane-anchoring Gag (Waheed and Freed, 2009), in addition to a group of positively charged residues within MA (Zhou et al., 1994).
